When the microscope was invented around 1590, suddenly we saw a new world of living things in our water, in our food and under our nose. But it's unclear who invented the microscope.
Attributed to the invention of the microscope are two Dutch spectacle craftsmen, Zacharias Jansen and his father Hans. In the waning years of the 16th century, their hands gave shape to the prototype of a device that has now become a cornerstone tool within various scientific domains.
The microscope, invented in the first quarter of the 17th century, was part of the Scientific Revolution, as it opened up whole new miniaturised worlds and avenues of scientific inquiry to challenge or confirm existing theories.
Robert Hooke, the English father of microscopy, re-confirmed Anton van Leeuwenhoek's discoveries of the existence of tiny living organisms in a drop of water. Hooke made a copy of Leeuwenhoek's light microscope and then improved upon his design.
1951: Erwin Wilhelm Müller invents the field ion microscope and is the first to see atoms. 1953: Frits Zernike, professor of theoretical physics, receives the Nobel Prize in Physics for his invention of the phase-contrast microscope.
Erwin Wilhelm Müller and his PhD student invented the Field Ion Microscope which was the first microscope capable of viewing atoms directly. The experiment involved placing a sharp tungsten tip inside a chamber of helium, cooling the tungsten to 21K, and electrifying it.
The history of the microscope spans centuries. Roman philosophers mentioned “burning glasses” in their writings but the first primitive microscope was not made until the late 1300’s. Two lenses were placed at opposite ends of a tube. This simple magnifying tube gave birth to the modern microscope.
The Yorkshire scientist Henry Power was the first to publish observations made with a microscope, and in 1661 Marcello Malphigi used a microscope to provide clinching evidence in support of Harvey's theory of blood circulation when he discovered the capillary vessels in the lungs of a frog.
Electron Microscopes: In 1931 Max Knoll and Ernst Ruska invented the first electron microscope that blasted past the optical limitations of the light. Physics dictates that light microscopes are limited by the physics of light to 500x or 1000x magnification and a resolution of 0.2 micrometers.
Three Dutch spectacle makers— Hans Jansen, his son Zacharias Jansen, and Hans Lippershey —have received credit for inventing the compound microscope about 1590. The first portrayal of a microscope was drawn about 1631 in the Netherlands. It was clearly of a compound microscope, with an eyepiece and an objective lens.
